WINDOW FILMS
Window film is installed on a glazing system
and adds functionality
Solar control window film
Minimize solar heat gain
UV blocking
While keeping visible light
Safety window film
Avoid flying glass shards in case of earthquake,
accidental breajakge, etc.
29
ARCHITECTURAL APPLICATIONS OF WINDOW FILMS
BENEFITS (ENERGY)
Energy savings
Reduces energy consumption by
• rejecting up to ~80% of solar energy in
summer
• reducing heat losses in winter
Decreases energy costs up to 30%
Reduces carbon footprint
Our architectural solar control window
films
reduce GHG emissions by 10 – 40% in
commercial buildings
30
WINDOW FILMS TECHNOLOGY
Typical solar control window film construction
- Laminate of optically clear PET films
- Functionalization through thin film – or wet
coating technology
- Mounting adhesives
- Acrylic PSA
- Polyester CDA
- UV absorbers
- Laminating adhesive
- UV curable acrylic hard coat
Core technologies
Roll to roll sputtering
• Wide web
• Metals, oxides
Coating and lamination
• Wide web
• High precision
• Ultra clear
31
CANADIAN WELL (HEAT EXCHANGER)
The Canadian well is a geothermal solution which provides
heated air in winter and cooled air in summer.
● Passive, although coupled to a mechanical ventilation system
ELIXAIR is a complete solution
● Reduction of energy spendings
● Natural thermal regulation
- Summer Comfort without air conditining
- Frost protection in winter
● Indoor air quality
32
PLANNING RENOVATION FOR ENERGY EFFICIENCY
33
SG QUICK U-VALUE OF BUILDINGS
 Thermal performance measurements are difficult
(DPE in France ; two weeks of co-heating measurement in UK)
 Need of a quick and accurate method for intrinsic performance
measurement: SG QUB
 QUB is a quick dynamical measurement
to assess the insulation level

34
THE U. SALFORD EXPERIMENT
 QUB comparison with static
measure in a full-scale climate
chamber
 House retroffited by stage
 Good agreement whatever is the
insulation level

circadian cycle) have been identified in the
eye about ten years ago
●
They are responsible of the Non-Visual

SAINT-GOBAIN SOLUTIONS FOR VISUAL COMFORT
Our solutions can influence visual comfort by several
aspects
Transparent products allow access to daylight and the
view
Translucent products allow daylight while avoiding glare
and preserving privacy
Active products can provide glare or privacy
management
Bright interior opaque products (wall, ceiling, floor)
contribute to the visual impression of spaces and
daylight quantity
Lighting products can be excellent complementary light
sources
Our solutions must be combined with good
architectural practices
56
DAYLIGHTING : BACK TO ENERGY EFFICIENCY
Energy efficiency is also a driver for natural lighting in buildings :

Studies show that by optimising the sound environment for both
communication and concentration, the company gets more profitable
New teaching methods creates acoustical challenges
Giving every child the best conditions for learning and
for personal development
Increasing knowledge and wellbeing
Studies show that students’ results for reading and learning correlate
directly to background noise levels
